On September 29 1764, the regiment was transferred to Ingolstadt to assume garrison duty.

Service during the War

In April 1757, the first battalion of the regiment was assigned to the Auxiliary Corps which was being assembled to serve with the Austrian Army on the basis of a subsidy contract settled with France on March 29. In July, its second battalion also joined this Auxiliary Corps which was assigned to the Austrian corps under the command of Count Nádasdy. In October, the regiment took part to the siege and capture of Schweidnitz. On November 22, both battalions were at the battle of Breslau where they formed part of the corps of Count Seyssel d’Aix on the right wing of the second line. A few weeks later, on December 5 at the battle of Leuthen, the regiment was part of Nádasdy's corps on the left wing. It was deployed in the center of this corps in the first line between the Leibregiment (on the left) and Preysing Infantry (on the right) near the Württemberger contingent whose fate they shared, being routed by the Prussian troops who attacked the flank of the left wing.

In April 1758, each Bavarian regiment contributed 1 company of fusiliers and 1 company of grenadiers to a converged regiment placed under the command of Colonel de la Rosée. During the siege of Olmütz, this converged regiment distinguished itself against the Prussian besiegers but it lost more than 100 men in these combats. In July, the various companies forming this converged regiment rejoined their respective units. In August, the Herzog Clemenz regiment took part to the siege of Neisse. After the withdrawal of the Prussians, the regiment counted only some 1,000 men.

In January 1759, the regiment returned to Straubing, its garrison place while one of its companies of grenadiers assumed garrison duty in Stadtamthof. The regiment remained in Bavaria till the end of the war.

Officers

The officers were distinguished by a silver lace on the tricorne which was also decorated with a black cockade fastened with a silver lace, and a silver gorget decorated with golden arms of Bavaria.

The horses of the mounted officers had a red shabraques and red pistol covers, all trimmed in yellow.

Musicians

Drummers wore the uniform of the troopers with the following distinctions:

white/blue woollen chevrons on the sleeves

white/blue laced swallow nest at the shoulders

white/blue laced cuffs

White bandolier edged white/blue.

The white drum barrel was decorated with blue flames and with the crowned arms of Bavaria. The hoops were decorated with white and blue stripes.

Colours

About the colours of the Bavarian infantry regiments , we know some models in use during the first part of the 18th century, before 1740; we know 4 models of flags which were in use between 1742 and 1745 and we also know the two models created in 1786 after the reunification of the bavarian and palatinate armies. So, between 1745 and 1786, information are unfortunately very scarce. The following descriptions represent an "educated guess" based on these few sources.

Bavarian regiments carried 2 colours per battalion. The first battalion of each regiment carried the Leibfahne and a Kompaniefahne while other battalions carried two Kompaniefahne.

For this regiment, we think the old Max Emanuel pattern could have been taken out the arsenal and carried again :

Please note that, as Ordinarfahne, the 1742-1745 pattern Type "2 (or even type "4") could have been carried, but without the double-head imperial eagle.
